DNZ Products announced their latest offering the Rapid Height tool which is designed to check for exact what height scope mount you need for when mounting a scope. I can see gun shops buying these things up! Pretty practical if you ask me.
DNZ Products states “A new, quick and easy to use measuring bar for checking what height scope mount you need to mount a scope. It will check height needed from top of firearm receiver or barrel to bottom of scope tube. The height can be checked and measured so you will know what height mount to use or to order.
You will also be able to see exactly how high off the barrel the scope will sit after mounting. This product will work with any mounting system made. This product can be used by anyone whether they use DNZ mounts or not. The heights will range from .33” to .78” in .03” increments. It can be used on 1”, 30MM, 34MM, and 35MM scopes. Made from milled Aluminum and clear anodized. Weight: 8 ounces.”
